the influence of flour content and immersion time in water on the creep behavior of composites made from high density polyethylene (hdpe) waste and mdf (medium density fiberboard) flour was investigated. mixing was carried out by a twin screw extruder and the sample was manufactured by flat hot press. firstly, the modulus of elasticity and bending strength of various mdf flour-polyethylene comp...

The water-soluble vitamins vary widely in chemical structure and properties, so it is not surprising that the characteristics of absorption of individual members of the group also show differences. Water-soluble vitamins are absorbed mainly into the blood, some very freely (e.g. ascorbic acid), others (e.g. thiamine) only in limited amounts. Vitamin Biz has an apparently unique mode of absorpti...

Octodon degus is a desert rodent of northern Chile, adapted to survive with a limited supply of water. This rodent has a high degree of fecal dehydration, related to colon water absorption. With the hypothesis that aquaporins (AQPs) might be present in the colon epithelium of O. degus and involved in fluid absorption, we studied colon water absorption in vivo and the distribution of AQPs and Na...

Iron is ubiquitous in natural water sources used around the world for drinking and cooking. The health impact of chronic exposure to iron through water, which in groundwater sources can reach well above the World Health Organization's defined aesthetic limit of 0.3 mg/L, is not currently understood. To quantify the impact of consumption of iron in groundwater on nutritional status, it is import...

dry beans are rich sources of dietary fiber and phytochemicals such as flavonoids and phenolics that exhibit good functional properties. in current study line, cooking and soaking time effects were investigated on water absorption, splitting and texture properties of different iranian red kidney beans to determine the best lines and the best soaking time for industrial use. d81083 line showed t...

for the purpose of increasing the permeability to oxygen and equilibrium water content in contact lenses, polar copolymers with nonionic monomers such as 2-hydroxyethle methacrylate(hema) is used. by adding the polar monomers to (hema), the permeability to oxygen and equilibrium with water content is increased and also the absorption of proteins on lens surface is changed. in this research, the...

BACKGROUND Hard water is associated with atopic dermatitis (eczema). We wanted to determine if a baby cleanser and its individual components altered free ionized calcium (Ca2+) in a simulated hard water baby bath. For these studies, an in vitro determination of free Ca2+ in a simulated hard water baby bath, and an in vivo exploratory study of free Ca2+ absorption into skin from hard water were ...
